"This was an act of extreme violence"

Sentencing at the court in Reading, Berkshire, Judge Paul Dugdale said: "Mark Sinclair - on Thursday, September 6, 2018 you murdered Kylie Dembrey, your partner of 12 years and the mother of your children, by stabbing her through the neck and heart.

"This was a murder with a knife, on a person you rendered unconscious, through strangulation, after years of domestic violence.

"This was an act of extreme violence, committed by you and I am sure in a violent rage.

"You took the life of a woman from a family who loved her; you took the life of a woman who loved you; you took the life of a woman you loved."
